Screw terminal blocks have many applications. They are useful both in homes and in industry. Their main task is to connect electrical wires. They also ensure the safety and durability of connections. In our practice, we often come across questions about the selection of appropriate terminal blocks. Customers appreciate our advice in this area.

Types of screw terminal blocks available at Onninen

Our offer includes various types of connectors. These include:

• Fused rail connectors
• Protective rail connectors
• Rail connectors through
• Protective threaded fittings
• Pass-through connectors in various colors

Each of these types has its own unique properties. Fused busbar connectors provide additional protection for circuits. Protective connectors are essential for installations that require grounding. Through-wiring models allow for easy connection of wires in a line.

It is worth paying attention to 2-wire through connectors. They are ideal for simple connections. Screw through connectors, on the other hand, guarantee a secure hold. For more demanding applications, we recommend threaded rail connectors. They provide the highest stability of connections.

1. Wire cross-section

Correct selection of connectors guarantees long-term and failure-free operation of the installation. Our experts will be happy to help you choose the optimal solutions.

Our experience shows that customers often underestimate the importance of selecting connectors. Meanwhile, they are the ones that determine the quality of the connections. Incorrectly selected ones can lead to failures. That is why at Onninen we focus on educating our customers in this area.
